3.3 Analysis of Diversity and Richness of Pollinators Communities
Diversity indices (Species richness, Shannon index) show that the open trail is comparatively more diverse, followed by the managed habitat (Table 2). The distribution of the pollinator species was much even in the open trail followed by Grassland. The species richness and Shannon Index is significant (t–test, p<0.05) in all of the habitats types. Similarly, similar evenness is observed in Forest trails and Grassland.
The highest number of species was found in the open trail (158), followed by the managed habitat (124), forest trail (103), and grassland (92). 61 species were common in all of the habitats, while the number of species exclusively found in one of the habitats was 12 for OT, 6 for FT, and 3 for MH (Figure 3). While comparing two types of habitats, the High number of habitats sharing of species was found between Open trail and Grassland (121) followed by Grassland and Forest trail (97), Managed habitat and Open Trail (82), and Grassland and Open Trail (68).
